To all whom it may concern:

Be it known that l, CLAnnNcn A. BUssnLL,

a citizen of the United States, residing at Carson, in the county of Pottawattamie and State of Iowa, have invented certain new and useful Improvements in Water-Circa lating Pumps for Internal-Combustion Engines, of which'the following is a specification. a i i This invention relates to an improved wa ter circulating pump particularly designed for use in connection with the engines of Ford automobiles, and has as one of its principal objects to provide a puinp which will. effectually prevent boiling of the water in the engine radiator. i

The invention has as a further object to providea pump so constructed that, when applied, it may be driven by the same fan belt employed for driving the fan of the vehicle motor.

Andthe invention has as a still further object to provide a pump which may be readily connected to a Ford engine without the necessity for structural change therein and which will proveentirely dependable and efficient in practical use. i i

Other and incidental objects will appear hereinafter,

in the drawings:

Figure 1 is a fragmentary side elevation showing my improved pump in connection with a Ford engine and radiator.

Figure 2 is a fragmentary front elevation showing the manner in which the impeller of the pump is driven,

Figure 3 is a longitudinal sectional view more particularly showing the structural details of the pump, and

Figure 4: is a transverse section on the line 44 of Figure 3, looking in the direction of the arrows.

Referring now more particularly to the drawings, I have, for convenience, shown my improved pump in connection with a Ford engine and radiator, the present pump being, as previously intimated, particularly designed for use with the engines of Ford automobiles. However, ll do not wish to be limited in this regard since, as will appear as the description proceeds, the pump'will prove efiicient wherever" found applicable. As is well known, the cooling system of a Ford engine does not include a pump and when the engine is subjected to heavy work serial at; asters.

or much hill climbing is done, it very often happens that the water in the radiator of the engine boils. This is, of course, objectionable since it not only causes loss of water but also tends toward overheating the engine. The present invention, therefore, seeks to provide a simple and effective pump which may be readily applied and which will maintain the water in constant circulation through the radiator. In Figure l, a Ford engine is conventionally illustrated at 10. In front of theengine is the radiator 11 having the usual bottom outlet 12 and top inlet 13 connected with thejacket of theengine cylinders. I The timing gear case of the engine is indicated at it and,as usual, this timing gear case is held in position by plurality of cap bolts 15. Upon the front of the engine crank shaft is fixed a pulley lo and mounted upon a suitable bracket at the front of the engine is the engine cooling fan 17 driven by a pulley 18. All of this structure is well known, being common in the construction of Ford engines.

(Joining now more particularly to the sub 5' ject of the present inventioml. employ a cylindrical pump casing 19 which, as partim ularly shown in Figure 3, is provided near its rear end with an outlet 20 upstanding from the upper side of the casing and hav. ing flanges 21 for connection to the engine block to register with the usual cylinder jacket inlet orifice therein, the cap bolts employed for securing the customary cylinder inlet connection to the block being used to extend through said flanges, Depending from the lower side of the casing near its forward end is a forwardly inclined inlet 22 i and connecting the outlet 12 of the radiator 11 with said inlet is a length of hose 23 se- 1 cured by appropriate hose clamps. Snugly fitting within the casing is a helical impeller or screw 24 having alined stub shafts 25 and 25' extending axially of the casing, the shaft 25 being provided near its forward end with a reduced journal 26. Journali'ng the shaft 25 is a closure plug 27 threaded into the casing at its rear end and recessed to receive the shaft. Extending through the casing at its upper side and threaded into said plug is an appropriate grease cup 28 in communication with said recess so that the bearing surfaces of the shaft and plug may be kept lubricated and, as will be ob served, the grease cup will coact with the of the engine.

casing for preventing accidental displacement of the plug. Threaded into the casing at its forward end is a closure plug 29 fitting the journal 26 of the shaft 25. As particularly shown in Figure at, the plug 29 is formed of mating semi-circular sections so that the plug may be readily assembled upon the shaft and, as will be perceived, the plug will coact with the journal 26 for holding the impeller against endwise movement. Extending through the casing at its upper side and threaded into the uppermost section oi the plug is an appropriate grease cup 30 in communication with the journal 26 so that the journal may be kept lubricated and said cup will, of course, coact with the casing forlocking the plug against rotation. it its miter end portion, the re cessed to provide a stufling box in which is arranged a suitable packing 31 and threaded into said recess is a nut 32 adjustable for binding the packing about the shaft 25. llllOUIltGCl upon the forward end portion 01 said shaft is a pulley 33 which is preferably adjustable along the shaft so that said pu ley may be alinedwith the pulleys l6 and 18, and trained over said pulleys is a suitable belt 34:. Thus, the pump will be driven alo with the lan from the engine crank she In order to support the casing 19 against the tension of the belt 34, said casing is provided near its forward end with a depending supporting arm 35 secured at its lower end by a cap bolt 36 supplanting one of the cap bolts 15 of the timing gear case -Accordingly, the arm will rigidly sustain the casing at its forward end. A drain cook 37 provides a means for emptying the casing.

As will now be readily understood in \lOW of the preceding description, when the engine is in operat10n,. the nnpellcr 2iol the 4. pump will be rotated so that water will be drawn in through the inlet 22 oi? the pump casing and discharged through the outlet 20 into the jacket of the engine cylinders so that the water will accordingly be caused to circulate through said ucket and through the engine radiator. In. thus causing the water to rapidly circulate through the in ui'or the water will, under ordinary ('UIH. L- tions, be kept below the boiling point so that waste of the water as well as possible overheating of the engine will be prevented. l accordingly provide a pump of highly Qllltftire design and a device which, as will now be readily understood, may be easily applied.

Having thus described the invention, what is claimed as new is:

A puinp having a COl'ltlDllOllS circuit, and including a ylindrical casing inserted in said circuit, a cylindrical screw 01": substuntially the same diameter and the some length as said casing and revolubly mounted there in, a pair of spaced shoulders formed on sail screw. :1 bearing ineiuber threaded in one (lid of said casing, said bearing member being split along an axial niedial plane to form two mating halves, each half engaging be tween said spaced shoulders, a packing box within said bearing inen'ibcr and means for revolving said screw.

In testimony whereof I aflix my signature.

CLARENCE A. RUSSELL.
